Steeda Underdrive Pulleys for Mach 1

Has Anyone use these Steeda Underdrive Pulleys on their Mach 1 with any results?

1996 - 2004 Mustang 4.6L GT Underdrive Pulleys


I have heard mixed reviews on the Under-drive pulleys for the Mach 1. Just wondering if anyone has any opinion on these or if they are worth the money.

Thanks - Brian

We have had nothing but great success with this pulley system. You will not be disappointed when you pull the trigger. PM if you have any additional questions I can answer for you?

Here is another Mach 1 member's testimonial "Steeda pulleys offer the best and will not blow out you oil pump and toast your motor, any other brand other than Steeda you do take a risk. I say this because Steeda has the pulleys balanced perfectly. I have gotten over 12hp to the wheels and approx 2.35+ mpg better with my Steeda pulleys and have had no problems".

You are in good hands with Steeda.

Thanks

If you plan on spinning that Mach to 6800-7000 rpms on a regular basis keep your stock crank damper. There's better mods for that motor..

Why would you say that? The Steeda Balancer is SFI certified, the OEM unit isn't. In the drag racing world that means the Steeda piece will not fail in racing conditions like the factory unit will.

I'll spare you the details about broken oil pump gears spinning the 4V modulars to 7K on a regular basis without the stock,ATI or Innovators West crank damper. UD pullies are fine for his car and will free up about 8-10RW. If he isn't a person who bangs the rev limiter and drives his car like a rental he'll be OK

You don't have to spare me any details, I've been doing this for just a little while.

And while I've seen a Innovators West crank damper kill several GT500 cranks, I've never seen our Steeda damper fail and cause an engine or oil pump issue 2V or 4V. If the customer is taking their motor to 7K regularly then they should know the consequences of high rpms.

haha then you shouldn't have questioned my first post saying to avoid changing the stock crank damper if spinning the motor to 7K on a regular basis... SO now your agreeing with me?
Can't say we've had any IW failures, just put one on a built 4V with a T-Trim getting installed in an old school Thunderbird Super Coupe
